I try not make make assumptions about another person based on how they want to fly a toy plane, just because its a different manner to what I choose..... W.T.F ?? [
] If you want to fly fast.. then go for it. I can't ever remember getting into jets because they flew slowly to be honest... As long as you keep it safe then I have no issue... A badly set up/ flown or maintained jet is going to do just as much harm at 250 Mph as it is 275!
What I can tell you is that I have logged a whole bunch ( Looking at my GSU it would suggest 65 to 70 flights) on my stock built Ultra Flash and its superb. Could I trade it or downgrade for a 120 or a P-80.... Hell No! I never was the biggest standard flash fan, but this Ultra is without a doubt leaps ahead better. It flies slow, it flies fast. It's pure, and its bloody strong. I get 8 mins on my set up ( Which is exactly the same time as my P-120 version flies for. I think the reason for this similar flight time, whilst having completely different performances is the bypass. Let me explain. Nothing too technical or aerodynamic here I am afraid guys. Just a simple guys evaluation based on stick time, and feel.
In California a few weeks ago, I got to fly a Titan powered UF of Afterburners. Whilst it flew just as well as either of my flashes back home, the top end speed was remarkably different. I was expecting some speed difference due to the power plant, but what I experienced really surprised me. With the non bypass install I found that in a dive the model would reach a speed and just stop accelerating. I would have the nose down, and be expecting the model to keep ramping up that little bit more... but nothing. Of course I could now see a big top end speed difference as well. What I also found was the massive drop in inertia and energy retention.
On My UF I can do a full power run and as I am getting to runway centre, cut the power ( My last pass of the day I actually shut the turbine off ) then pull to vertical. On the energy alone I then let it climb vertically. With my bypassed model I get to a dot ( Almost out of sight ) I can then do almost 3 mins on the glide till touch down. Although normally I just do a sequence of aeros. With the open install, it was as if I had a huge air brake on. The vertical climb was cut in half, and then the subsequent dive was much shorter and harder work.
I will have a UF in the fleet from now on, no mater what. That UF will have a powerful turbine, no matter what. That bigger turbine will be fully bypassed... no mater what
Thats not to say that the model performs badly on the open install. I had a blast flying the UF of Afterburner in Cali ( Thanks again for) It's just that I think its a slightly better all round set up when its all cleaned up internally.
Hope this feed back helps? and I hope you guys keep enjoying your UF's. They are a great plane, and if you get half as much out of yours as you do mine, you will be happy.
